Experimentalists send a signal, detect its arrival and determine its speed: the speed is (e.g. four times) greater than 300000 km/s. At least that is what the public should know:

The Criminal Relativity Cult (CRC) have sanctioned the information on condition that experimentalists should call the signal "Hamlet" and convince the public that, although the signal exists (after all, one sends it and detects its arrival), it nevertheless does not exist. More precisely, the signal should be deprived of any information and then it is clear that if something is deprived of any information, it simply does not exist. And if something does not exist, it can by no means threaten divine theory of relativity.

 

However CRC soon discover that "total informationlessness" is too contradictory or at least that the public would not believe this particular version of the lie:

So CRC have studied carefully a moving picture of Hamlet:

and found their last resort: Hamlet cannot move before the front end of the waves and since the speed of the front end cannot surpass 300000 km/s.... Why Hamlet should be sent together with the front end is for the moment a grand secret in CRC: the initiated don't wish to think of a Hamlet sent after the front end has reached its destination.

Pulse reshaping (anomalous dispersion) does not violate causality.

Excellent answer, swansont. There appears to be no contention to it.
